Letters Patent No. 90,190, dated May 18, 1869.

IMPROVED HOLDER FOR SCREW-CUTTIN DIES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom tt may concern:

Be it known that I, Anser. PHINNEY, of Bainbridge, in the county ofChenango, and State of New York,

have invented a new and useful Improvement in Hold-V ers forScrew-Cutting Dies; and I do hereby declare that the followingisa full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specication, vin which-Figure 1 represents a sectional elevation of my im proved device, takenon the line xa: of g. 1, and

Figure 2 represents a horizontal section of the same, taken on the liney y of Eig. l. v

Figure 3 represents aside elevation of my improved holder.

Similar letters of reference indicate like parts.

The object of this invention is to provide an improved bolder ordie-plate for dies for cutting screws.

It consists in the construction and arrangement of parts, as will behereinafter more fully described.

A represents a die-plate, in which the dies are secured in the ordinarymanner, to one face of which the crotched shank B is connected, at rightangles thereto, the outer end of which is fitted to be inserted in ahand-brace or bit-stock, as shown at C.

By this arrangement, it is believed that a much better control of theaction of the dies may be had, and that they may be operated much fasterthan with the plates, as now constructed.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The constructionand arrangement of the die-plate A, having the dies and set-screw, andthe crotched shankiB, terminating in the end, G, adapted to f t in abit-stock, herein described, for the purpose specified.

ANSEL PHINN EY.
